Remote sensing
Use remote sense where the load regulation at the load end is critical. In remote sense,
the power
supply will compensate for voltage drop on the load wires. Refer to the power supply specific
a
tions for
the maximum voltage drop on load wires. The voltage drop is subtracted from the total voltage avai
l-
able at the output. Follow the instructions
below to configure the power supply for remote sensing:
1.
Ensure that the AC On/Off is in the Off position.
2.
Remove the local sense jumpers from J2.
3.
Connect the negative sense lead to terminal J2
-
5 (
-
S) and the positive sense lead to term
i
nal J2
-
1(+S) of the
J2 mating connector. Ensure that the J2 mating connector is plugged securely into
the rear panel sense connector, J2.
4.
Turn On the power supply.
Notes:
1.
If the power supply is operating in remote sense and either the positive or negative load wire is not
co
nnected, an internal protection circuit will activate and shut down the power supply. To resume
operation, turn the AC On/Off to the Off position, connect the open load wire, and turn On the
power supply.
2.
If the power supply is operated without the remote
sense lines or local sense jumpers, it will co
n-
tinue to work, but the output voltage regulation will be degraded. Also, the OVP circuit may act
i-
vate and shut down the power supply.

sales or se
r-
vice facility near you for Return Authorization and shipping information. Please attach a tag to the
power supply describing the problem and specifying the owner, model number and serial number of
the power supply. Refer to Wa

nty Information for further instructions.
WARNING
There is a potential shock hazard at the sense point when using a power supply
with a rated Output Voltage greate
r than 40V. Ensure that the connections at the
load end are shielded to prevent accidental contact with hazardous voltages.
CAUTION
When using shielded se
nse wires, ground the shield in
one place only. The location can be the power supply
chassis or one of the output terminals.
